Claims

[Scope of utility model registration request]

In order to laminate different types of ceramic materials above and below an effective layer sandwiched between internal electrodes that provide capacitor characteristics, different types of ceramic materials are layered at the bonding interface between the effective layer and the inactive layer that is not surrounded by the internal electrodes. A heterogeneous ineffective layer type characterized by having a structure that relieves thermal stress generated at the interface between the ineffective layer and the effective layer by sequentially stacking sheets with a low mixing ratio to sheets with a high mixing ratio toward the effective layer. Multilayer ceramic capacitor.
